  Verfahren zur Herstellung eines neuen, als Hilfsmittel für die Textilindustrie       wertvollen        Estergemisches.       Es wurde gefunden, dass man ein neues,  als Hilfsmittel für die Textilindustrie wert  volles, aus dem Mono- und     Di-p-kresylcar-          bonsäureester    bestehendes,     Estergemisch    er  hält, wenn man     Phthalsäure-R-sulfosäure    oder  ein solches Derivat derselben, das durch Be  handlung mit einem Phenol in einen Ester  der     Phthalsäure-@-srilfosäure    übergehen kann,  wie das     Anhydrid    oder die     Halogenide    dieser  Säure,

   mit     p-Kresol    behandelt.  



  Zur     Veresterung    kann man beispielsweise       Phtlialsäure-ss-sulfosäure    beziehungsweise de  ren     Anhydrid    oder Chlorid mit     p-gresol     erhitzen. Die     Veresterung    wird erleichtert,  wenn man das bei der Reaktion sich bildende  Wasser aus dem     Veresterungsgemisch    in be  kannter Weise entfernt, beispielsweise mit  Hilfe solcher Stoffe, die mit Wasser     azeotrope     Mischungen bilden. Statt von den Säure  chloriden auszugehen, kann man dieselben  auch erst während der     Veresterung    entstehen  lassen, zum Beispiel unter Anwendung von         Phosphoroxychlorid    und dergleichen.

   Die zu  veresternde     Phthalsäure-ss-sulfosäure    braucht  nicht in reinem Zustande vorzuliegen, man  kann dieselbe auch in der Form verwenden,  die man erhält, wenn man     Phthalsäureanhy-          drid    durch Erhitzen mit     Schwefelsäureanhy-          drid    unter Druck     sulfiert    und die     Sulfiermasse     vom grössten Teil des überschüssig angewen  deten     Sulfonierungsmittels    befreit.  



  Das neue     Estergemisch    stellt nach dem  Neutralisieren und Trocknen ein gelbliches  Pulver dar, das in Wasser leicht löslich ist  und ein ausgesprochenes Netz-,     Reinigungs-          und        Emulgierungsvermögen    besitzt. Das Ester  gemisch kann daher für die mannigfaltigsten  industriellen Zwecke Verwendung finden.  



  <I>Beispiel:</I>  22,8 Gewichtsteile     Phthalsäureanhydrid-          ss-sulfosäure,    welche zum Beispiel durch län  geres Erhitzen der freien     Sulfosäure    im Va  kuum erhalten werden kann, und 21,6 Ge-           wichtsteile        p-gresol    werden unter Rühren  auf 110   C erhitzt. Man lässt auf etwa 50   C  erkalten und fügt bei dieser Temperatur  11,2 Gewichtsteile     Phosphoroxychlorid    tropfen  weise hinzu. Die     blasse    wird etwa 15 Minu  ten auf     95-100('    C gehalten und dann wäh  rend etwa 45 Minuten auf 100-110   C er  hitzt, bis fast kein     Salzsäuregas    mehr abge  spalten wird.

   Das     Veresterungsprodukt    wird  in Wasser gelöst und     ausgesalzen.    Nach dein  Trocknen erhält man ein gelbliches Pulver,  welches zum Beispiel in Wasser gut netzt.



  Process for the production of a new ester mixture which is valuable as an auxiliary for the textile industry. It has been found that a new ester mixture, which is valuable as an aid for the textile industry and consists of the mono- and di-p-cresylcarbonic acid ester, is obtained if phthalic acid-R-sulfonic acid or such a derivative thereof is used Treatment with a phenol can convert into an ester of phthalic acid - @ - srilfosäure, such as the anhydride or the halides of this acid,

   treated with p-cresol.



  For the esterification, for example, phthalic acid-β-sulfonic acid or its anhydride or chloride can be heated with p-gresol. The esterification is facilitated if the water formed during the reaction is removed from the esterification mixture in a known manner, for example with the aid of substances which form azeotropic mixtures with water. Instead of starting from the acid chlorides, they can also be left to form during the esterification, for example using phosphorus oxychloride and the like.

   The phthalic acid-ß-sulfonic acid to be esterified need not be in the pure state; it can also be used in the form which is obtained when phthalic anhydride is sulfated by heating with sulfuric anhydride under pressure and most of the excess is sulfated applied sulfonating agent freed.



  After neutralization and drying, the new ester mixture is a yellowish powder that is easily soluble in water and has excellent wetting, cleaning and emulsifying properties. The ester mixture can therefore be used for a wide variety of industrial purposes.



  <I> Example: </I> 22.8 parts by weight of phthalic anhydride ß-sulfonic acid, which can be obtained, for example, by heating the free sulfonic acid for a long time in a vacuum, and 21.6 parts by weight of p-gresol are stirred up 110 C heated. The mixture is allowed to cool to about 50 ° C. and 11.2 parts by weight of phosphorus oxychloride are added dropwise at this temperature. The pale is kept at 95-100 ° C for about 15 minutes and then heated to 100-110 C for about 45 minutes until almost no more hydrochloric acid gas is split off.

   The esterification product is dissolved in water and salted out. After drying, you get a yellowish powder, which wets well in water, for example.
